Mesopotamia is a historical region of West Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. Today, Mesopotamia is known as present-day Iraq. In the broader sense, the historical region of Mesopotamia also includes parts of present-day Iran, Turkey, Syria and Kuwait.
The 3rd millennium BC spanned the years 3000 to 2001 BC. This period of time corresponds to the Early to Middle Bronze Age, characterized by the early empires in the Ancient Near East. In Ancient Egypt, the Early Dynastic Period is followed by the Old Kingdom. In Mesopotamia, the Early Dynastic Period is followed by the Akkadian Empire. In what is now Northwest India and Pakistan, the Indus Valley civilization developed a state society.
The 25th century BC comprises the years from 2500 BC to 2401 BC.
The 23rd century BC was a century that lasted from the year 2300 BC to 2201 BC.
Sumer is the earliest known civilization, located in the historical region of southern Mesopotamia, emerging during the Chalcolithic and early Bronze Ages between the sixth and fifth millennium BC. Like nearby Elam, it is one of the cradles of civilization, along with Egypt, the Indus Valley, the Erligang culture of the Yellow River valley, Caral-Supe, the Cucuteni–Trypillia culture of the Carpathian Mountains, and Mesoamerica. Living along the valleys of the Tigris and Euphrates rivers, Sumerian farmers grew an abundance of grain and other crops, a surplus which enabled them to form urban settlements. The world's earliest known texts come from the Sumerian cities of Uruk and Jemdet Nasr, and date to between c. 3350 – c. 2500 BC, following a period of proto-writing c. 4000 – c. 2500 BC.
The history of Sumer spans the 5th to 3rd millennia BCE in southern Mesopotamia, and is taken to include the prehistoric Ubaid and Uruk periods. Sumer was the region's earliest known civilization and ended with the downfall of the Third Dynasty of Ur around 2004 BCE. It was followed by a transitional period of Amorite states before the rise of Babylonia in the 18th century BCE.
The 29th century BC was a century that lasted from the year 2900 BC to 2801 BC.
Dangun or Tangun, also known as Dangun Wanggeom, was the legendary founder and first king of Gojoseon, the first Korean kingdom. He founded the first kingdom around the northern part of the Korean Peninsula. He is said to be the "grandson of heaven", "son of a bear", and to have founded the first kingdom in 2333 BC. The earliest recorded version of the Dangun legend appears in the 13th-century Samguk yusa, which cites Korea's lost historical record, Gogi and China's Book of Wei.
Gojoseon, contemporary name Joseon, was the first kingdom on the Korean Peninsula. According to Korean mythology, the kingdom was established by the legendary king Dangun. Gojoseon possessed the most advanced culture in the Korean Peninsula at the time and was an important marker in the progression towards the more centralized states of later periods. The addition of Go, meaning "ancient", is used in historiography to distinguish the kingdom from the Joseon dynasty, founded in 1392 CE.
Gaecheonjeol is a public holiday in South Korea on 3 October. Also known by the English name National Foundation Day, this holiday celebrates the legendary formation of the first Korean state of Gojoseon in 2333 BC. This date has traditionally been regarded by Koreans as the date for the founding of the Korean race.
Ancient literature comprises religious and scientific documents, tales, poetry and plays, royal edicts and declarations, and other forms of writing that were recorded on a variety of media, including stone, clay tablets, papyri, palm leaves, and metal. Before the spread of writing, oral literature did not always survive well, but some texts and fragments have persisted. One can conclude that an unknown number of written works too have likely not survived the ravages of time and are therefore lost.
The Civilization of Mesopotamia ranges from the earliest human occupation in the Paleolithic period up to Late antiquity. This history is pieced together from evidence retrieved from archaeological excavations and, after the introduction of writing in the late 4th millennium BC, an increasing amount of historical sources. While in the Paleolithic and early Neolithic periods only parts of Upper Mesopotamia were occupied, the southern alluvium was settled during the late Neolithic period. Mesopotamia has been home to many of the oldest major civilizations, entering history from the Early Bronze Age, for which reason it is often called a cradle of civilization.
The three Gojoseon kingdoms are states thought to have existed according to Joseon Sangosa (1924–25). The concept gained a following among several fringe historians, although it is not completely accepted by mainstream scholars.
The Early Dynastic period is an archaeological culture in Mesopotamia that is generally dated to c. 2900 – c. 2350 BC and was preceded by the Uruk and Jemdet Nasr periods. It saw the development of writing and the formation of the first cities and states. The ED itself was characterized by the existence of multiple city-states: small states with a relatively simple structure that developed and solidified over time. This development ultimately led to the unification of much of Mesopotamia under the rule of Sargon, the first monarch of the Akkadian Empire. Despite this political fragmentation, the ED city-states shared a relatively homogeneous material culture. Sumerian cities such as Uruk, Ur, Lagash, Umma, and Nippur located in Lower Mesopotamia were very powerful and influential. To the north and west stretched states centered on cities such as Kish, Mari, Nagar, and Ebla.
The art of Mesopotamia has survived in the record from early hunter-gatherer societies on to the Bronze Age cultures of the Sumerian, Akkadian, Babylonian and Assyrian empires. These empires were later replaced in the Iron Age by the Neo-Assyrian and Neo-Babylonian empires. Widely considered to be the cradle of civilization, Mesopotamia brought significant cultural developments, including the oldest examples of writing.
The Early Assyrian period was the earliest stage of Assyrian history, preceding the Old Assyrian period and covering the history of the city of Assur, and its people and culture, prior to the foundation of Assyria as an independent city-state under Puzur-Ashur I c. 2025 BC. Very little material and textual evidence survives from this period. The earliest archaeological evidence at Assur dates to the Early Dynastic Period, c. 2600 BC, but the city may have been founded even earlier since the area had been inhabited for thousands of years prior and other nearby cities, such as Nineveh, are significantly older.
The mid-24th century BCE climate anomaly is the period, between 2354 and 2345 BCE, of consistently reduced annual temperatures that are reconstructed from consecutive abnormally narrow, Irish oak tree rings. These tree rings are indicative of a period of catastrophically reduced growth in Irish trees during that period. This range of dates also matches the transition from the Neolithic to the Bronze Age in the British Isles and a period of widespread societal collapse in the Near East. It has been proposed that this anomalous downturn in the climate might have been the result of comet debris suspended in the atmosphere.
King of Sumer and Akkad was a royal title in Ancient Mesopotamia combining the titles of "King of Akkad", the ruling title held by the monarchs of the Akkadian Empire with the title of "King of Sumer". The title simultaneously laid a claim on the legacy and glory of the ancient empire that had been founded by Sargon of Akkad and expressed a claim to rule the entirety of lower Mesopotamia. Despite both of the titles "King of Sumer" and "King of Akkad" having been used by the Akkadian kings, the title was not introduced in its combined form until the reign of the Neo-Sumerian king Ur-Nammu, who created it in an effort to unify the southern and northern parts of lower Mesopotamia under his rule. The older Akkadian kings themselves might have been against linking Sumer and Akkad in such a way.
